Odd MKV file

Post by Osmolar »

Ran into another file that Handbrake refuses to encode... looked in the log and found this:

Code: Select all

Input #0, matroska, from '/Users/dan/Desktop/Rudy.mkv':
  Duration: 01:53:59.87, start: 0.000000, bitrate: N/A
    Stream #0.0(eng): Video: h264, yuv420p, 1280x692, 23.98 tb(r)
    Stream #0.1(eng): Audio: ac3, 48000 Hz, 5:1, s16
    Stream #0.2: Attachment: 0x0000
    Stream #0.3: Attachment: 0x0000
    Stream #0.4: Attachment: 0x0000
I don't know if this is what is giving HB the problem, just seems odd that this MKV would have three seemingly empty streams. Any MKV experts have out there have a clue into what's going on here?

They may not be empty, they may just contain material that HB doesn't know how to handle. mkvinfo may be able to correctly identify the attachments.

Thanks, Ted...

Well, I ran that tool in Crossover and from what I see, they appear to be fonts. I am assuming these are for some sort of embedded subtitling? This movie has no hard subtitles that I have ever seen.

When I did the original rip and encode, I did not embed fonts into the MKV (didn't even know this was possible). Is it possible the old MKV encoder I used "stamped" the video with some sort of watermark? Or maybe they were for a scene where the location in the movie is displayed? I'm lost and a complete noob at this stuff.

It's possible, but Handbrake certainly doesn't have the functionality to embed soft subs and associated fonts.

You could use the mkvmerge GUI from the same package to extract the attachments and re-write the file.

Do you have a full log? Attachments shouldn't matter, both in 0.9.3 and SVN

Sorry, going to play devil's advocate here...

How would you have created a MKV file and not know what the contents of it are?

Not 100% certain what you're implying here, but am fairly sure and find it fairly presumptious. As I stated in my earlier post, I'm no expert when it comes to this stuff. Last year, I ripped most of my Blu-Ray disks on my Windows box and converted them to MKVs following a guide I found on videohelp.com. I really haven't the foggiest idea how there are fonts embedded in this file, nor do I even know why you would even need them. I only noticed the extra attachments when I compared the log to a known successful one.

What I do know, is I followed TedJ's sage advice on removing the attachments and was able to successfully use Handbrake to encode an Apple TV compatible version overnight. Thanks, Ted.
